Pressure Reducing Regulators from Equilibar

Pressure Reducing Regulators for Air and inert gases

Pressure Reducing Regulators (PRR) are the most common type of pressure regulator. They reduce an unregulated inlet pressure down to a desired regulated outlet pressure ( learn more).

The manual PRRs listed below are recommended for use as pilot pressure regulators for Equilibar back pressure regulators. All PRRs listed are designed for use with air or inert gas* and have a small but significant weep to the atmosphere.

Contact an application engineer for assistance in selecting the ideal Pressure Reducing Regulator for your application.

* Note: All pressure regulators listed are designed for air service and have a small but significant weep to the atmosphere (see specific product brochure for details). Customers may consider adapting one of these air regulators for inert gas service provided they deploy the devices in a well ventilated space and are technically competent to analyze all the potential risks associated with the installation.
